First Claim
Patent Images
1. A mobile holding furnace, comprising:
- a container for holding molten metal;
means for maintaining the molten metal in a liquid state while in the container;
an outlet in fluid communication with the container through which molten metal can be dispensed, the outlet being disposed toward the upper portion of the container;
a pump disposed at least partially within the container for dispensing discrete quantities of molten metal from the container;
a frame atop which the container is disposed;
a plurality of wheels atop which the frame is disposed, the wheels permitting the frame to be moved from place to place;
spaced tracks adapted to receive the wheels, the tracks adapted to be disposed adjacent individual molds;
a latch connected to the tracks, the latch engageable with the frame to secure the frame in a stationary position relative to the tracks; and
an extensible connection disposed intermediate the latch and the frame, the extensible connection permitting the frame to be adjusted short distances relative to the tracks.

Abstract
A mobile holding furnace having a metering pump is adapted to hold a relatively small quantity of molten metal in a contamination-free condition for dispensing to individual molds. The furnace is provided with insulation and electric heating elements for maintaining the molten metal in a liquid state. The furnace is sealed such that an atmosphere of inert gas can be maintained above the level of molten metal. The furnace is mounted upon wheels for easy transportation from place to place. The furnace is used in conjunction with tracks disposed adjacent individual molds, the tracks permitting the furnace to be locked in place while molten metal is dispensed into the molds.

16. A mobile holding furnace, comprising:
-
a container for holding molten metal; means for maintaining the molten metal in a liquid state while in the container; an outlet in fluid communication with the container through which molten metal can be dispensed; dispensing means disposed at least partially within the container for dispensing discrete quantities of molten metal from the container through the outlet; and reservoir means disposed beneath the container for receiving molten metal discharged from the container upon rupture of the container.

17. A mobile holding furnace, comprising:
-
a container for holding molten metal; means for maintaining the molten metal in a liquid state while in the container; means for controlling the chemical content of the atmosphere above the molten metal in the container; an outlet in fluid communication with the container through which molten metal can be dispensed, the outlet being disposed toward the upper portion of the container; a pump disposed at least partially within the container for dispensing discrete quantities of molten metal from the container; a frame atop which the container is disposed; and a reservoir secured to the underside of the frame beneath the container, the reservoir adapted to receive molten metal discharged from the container upon rupture of the container.
